Be it known that I, WALTER a citizen of the United States, Wilkinsburg, in the county of Allegheny and State of Pennsylvania, have invented and useful Improveme ts in Protectors for Contact-Fingers, of which the following is a specification.

This invention relates to hand operated electric controllers and has for its principal object to provide means for protecting the contact fingers.

It sometimes happens that the contact fingers of a controller are bent out of position by an unskilled operator, so that the finger may 'not make contact in the position-intended.

In order to prevent this, incase each-finger in'such a manner that the 20 finger will be inaccessible for bending so far ,as the ordinary operator on the roadis con;

,cerned.

a In the accompanying drawing; Figure 1' I 's a transverse 3 troller, showing the finger protecting device applied; Fig. 2 a face v1ew of the protecting V. TURNER,

devlce; Fig.3 a side elevation thereof n Fi 4' a plan view.

is shown in the drawing, the protecting 1 having base 2 for securing same to the insulation block 3 in the controller casing 4. e

ithin the casing 1 is mounted the usual contact finger 5 adapted to engage the usual contacts 6 of the controller drum. 1

The protecting casing incloses the finger on all sides, but has an opening 7 through a s as Specification of Letters Patent.

' which thecontact finger projects so as to engage the drum contacts."

In order to still further prevent the possible excessive bending of the finger, the finger may be provided with a projection 8 which engages the inner wall of the casing when it is attempted to bend the finger outwardly.

Having now described my invention, what I claim as new and desire to secure by Letters Patent, is: I

1. The combination with an electric controller having a contact finger, of a casing mounted within the controllerv and separately inclosing said contact fin er and having an opening through which t e finger projects. '2. The combination with an electric controller having a contact finger,.'of an individual casing mounted within for separately inclosing only the contactfinger and provided with an opening of limited extent through which'the contact finger is,

adapted to-"make contact.

. .3. The combination'with an electric controller having a contact finger, of a casing hood mounted in the controller and locally having a restricted which a portion of the conopening through said contact finger havtact finger pro1ects, in walls of the hood and outward movement of the said opening.
